Is the First Gen RX7 a good fit with ITB? Most likey it is. However, when I have been included with the ITB and ITC cars I have been midpack at best. This is largely due to a lack of tuning and seat time on my part. At Nelson Ledges this year , I ran in the 1:26-1:28 range, and Scott Nutter, who has much more experience at NL runs 1:22's with his RX7. The top ITB car turns a 1:19 and a significant percentage of the other ITB cars were in the1:20 -1:24 range. Is this data relevant? Who knows? There are alot of unknown variables. Although, I do not think the RX7 would be an overdog in ITB even in its current legal trim.
If the RX7 is moved to ITB, I suspect additional weight will be will be one of the penalties. However, the 6" rim requirment will be the one that stings the most. In my situation, I will not be able to use four Circle rims ($890) and four Diamond rims ($450). I would then have the choice of utilizing the stock 5.5 rims or buying new six inch rims.
In other posts on current threads, the response to a complaint about 6" rims has been met with the solution of selling the 7" rims on Ebay. What kind of market exists for 13" by7" used racing rims? I plead ignorance here. It will not be the "Import" crowd. They want 18" rims.
Maybe I am in the minority here, but I do not see a tremendous performance advantage of 7" rims nor do I have vast financial resouces to throw into racing.
In this situation, if the RX7 is moved to ITB, I want SCCA to be sensitive to the finacial impact it will have on the middle class racer. For most of us, we will end up eating a good percentage of our wheel inventory. A new set of steel 6" rims is about two entry fees. Would it be plausible to allow 7" rims in ITB with an addional weight penality?
I intend to express these thoughts with a letter to the Comp. Board.
In another respect, I would rather see IT7 in the NE.
